TRMS Digital Multimeter with Analog Bar Graph and Temperature Measuring Instrument

Multimeters of the economy series METRALINE are auto-range devices for universal use in all areas of electro-technics. They provide the user with the time-tested safety and reliability from Gossen Metrawatt at a convincing price performance ratio.

The METRALINE DMM15 provides users with all the measuring functions of a highly diverse multimeter: convincing technology with all voltage, resistance, current and temperature measuring ranges, and additional measuring functions and automatic functions.

Features in Detail:

Automatic Blocking Sockets (ABS) *
Automatic blocking sockets prevent incorrect connection of measurement cables and inadvertent selection of the wrong measured quantity. This significantly reduces danger to the user, the instrument and the system under test, and eliminates it entirely in many cases.
* Patented (patent no. DE 10 2005 062 624, US 7,439,725)

Automatic / Manual Measuring Range Selection
Measured quantities are selected with the rotary switch. The measuring range is automatically matched to measured values. The measuring range can be selected manually as well with the help of the AUTO/MAN key.

Display of Negative Values at the Analog Scale
Negative values are also displayed at the analog scale for zerofrequency quantities, allowing for observation of measured quantity fluctuation around the zero-point.

Storage of Measured Values
By pressing the HOLD/MIN/MAX key, the currently displayed measurement value can be „frozen“ in the display. The minimum and maximum values which were present at the input of the measuring instrument after activation of the MIN/MAX mode can be selectively "retained" with the MIN/ MAX function. The most important application is the determination of the minimum or maximum value during long-term observation of measurement quantities. MIN/MAX has no effect on the analog display; it continues to display the current measurement value.

Continuity Test
Allows for the detection of short-circuits and interrupted conductors. In addition to displaying test results, an acoustic signal can also be generated if desired.

Power Saving Circuit
The device is switched off automatically if the measured value remains unchanged for a period of approximately 10 minutes, and if none of the controls are activated during this time. Automatic shutdown can be deactivated.

Protective Cover for Harsh Conditions (optional)
The instrument is protected against damage in the event of impacts or dropping by means of a soft rubber cover with tilt stand. The rubber material also assures that the instrument does not wander if it is set up on a vibrating surface.

RMS Measurement with Distorted Waveshapes
The measuring method applied allows for RMS measurement for alternating signals (AC) in voltage and current measurement, independent of the waveshape up to 1 kHz (for non-sinusoidal signals as well).
